Hey everyone, I have a 95 4WD blazer with transmission isssue's. Shifts great up and down in every gear, but when doing freeway speeds in overdrive, if I give it a little gas it'll drop a gear easy, but give it a little to much gas and it goes into neutral and revs up. Remove my foot from the gas and it slams hard back into gear and everything seems fine afterwards. Tranny Fluid is fresh and is topped up, and was rebuilt about 50,000miles ago i'm thinkin maybe eletrical issue maybe?

On an '02 Blazer, 68K, 2wd Transmission is downshifting too quick, and holding gear a bit long before shifting. No other problems, just acts like it is mis-reading the speed and load. All shifts are good, drops right into gear, both forward and reverse, no weird noises. Tranny was serviced about 5K ago, no trash in the pan, no burned fluid, all looks good. I guess the best way to describe what it is doing is it acts like it is in tow-haul mode, even though that isn't an option on this vehicle. Now, I should point out that this is a Blazer xTreme, and has had the ECM flashed to factory specs. I am told that the xTreme does have different operating parameters than a standard Blazer since it has a lowered suspension, handling package, and high speed rated tires. We also have a '99 standard Blazer, and the drive train definitely behaves more sedately. xTreme editions are very rare in the part of the country, so I cannot find one to compare it to. Thoughts? |

I recently bought a 1998 Blazer that hadn't been run in 2.5 years. I got it running quite easily and checked the tranny fluid level when the engine was cold and it registered way above full/hot. I took it for a test ride to get the fluid hot and rechecked the fluid. It didn't even register on the dip stick. I added almost 3 quarts of tranny fluid and got the level up to where it should be with a hot engine. I ran it for a couple of weeks and started noticing tranny fluid puddles after everytime I drove it. The leak isn't coming from the transmission area but from somewhere in the front of the engine compartment. There's a plastic shroud under the front of the engine/radiator that restricts me from seeing the source of the leak. I recently rechecked the tranny fluid while hot and it's barely registering at all on the dip stick but when the engine is cold the fluid level shows over full. Where do I start?

Replying to: kruz (Jul 30, 2008 1:09 pm) And there is a supply line and a return line that go from the transmission to the radiator and back to provide cooling for the tranny. If you are seeing fluid up near the radiator, one of those lines or the connection to the radiator is bad. Follow the lines all the way to where they connect to the radiator (passengers side, near but below the battery) and you should see the leak. |

| My sister has a 97 GMC Jimmy and has been having the "stuck in third gear" issue. Tried replacing the ignition switch and it didn't help. Resetting computer didn't help. Was thinking about digging in and just replacing all the solenoids in the transmission along with the filter and fluid. But then I found the TSB for this exact issue so now my thinking has shifted in a completely different direction. She lives over an hour away but as soon as I get a chance will be checking fuses and the wiring and voltage to transmission. TSB mentions cause being aftermarket remote starter installed which my sister had until I replaced ignition switch. Hopefully I get this fixed soon and maybe this will help some of you out too.
